§ 64-04-03 — Specification of liquid gas meters

All liquid gas meters must be of a positive displacement type equipped with a vapor
separator or provided with other equipment which will positively eliminate all air and vapor from
passing through the meter with the liquid gas, and a differential pressure regulator. The meters
must be corrected, prior to use, to sixty degrees Fahrenheit [15.5 degrees Celsius] liquid gas
temperature and all deliveries of liquid gas through such meters must, at the time and place of
delivery, be temperature-corrected to sixty degrees Fahrenheit [15.5 degrees Celsius] and the
customer billed accordingly. It is unlawful to make retail sales to customers except where
delivered through a fuel dispenser from any bulk delivery vehicle unless such bulk delivery
vehicle is equipped with and dispenses said liquid petroleum gas through a liquid meter as
herein provided. Liquid meters may not be equipped with a bypass around the liquid meter. The
prohibition of a bypass does not prohibit the use of an equalization line.
